A ROBOT LOOKOUT
INGENIOUS INVENTION FOR SHIPS. An ingenious course direction finder for the use of ships has just been produced at the Radio Research Station, Slough. Once the course is set, the slightest deviation is shown by the switching on of a light, green if the deviation is to starboard and red if the deviation is to port. The device is called the cathode ray oscillagraph. A white light glows as long as the course is followed closely, switching off as soon as there is any deviation, when the coloured lights come into play.
